latest version hct2(2020/12/17) bricked wont let downgrade - MTCD Android Head Units General

I soft bricked my device by uninstalling easyconnet app with root.
Device now goes black after boot logo.
I tried an update from previous version, but it gives error that it can not be downgraded.
current version hct2.20201217.142203
Can anyone help out how to get out of this mess I made?
Is there a way to install updates from previous versions?
Can I install OLS_rk3399_10.0_ota(20201229).rar? Which is the only one I found that is newer.
Dicola supplier did not respond when asked for firmware on aliexpress. They dont seem to have a website.

I'm not sure which one you mean.
I do not have an sd card reader in my radio.
The only one i see that is newer from your thread is from xybertechnics
Code:
These seem to be newer? I installed these today:
PX6 android 10 (20210111)https://drive.google.com/file/d/1dDoDqUEmbaSIexqEzHW5_K1_QDAFJlhG/view?usp=sharing
MCU and updates 3.71 MCU https://drive.google.com/file/d/1nfEXeXJ79FJC21hGXE6GqDC-oRd3o8cx/view?usp=sharing
What is the mcu update?
If i update mcu to this 3.71 can i downgrade after?

Just in case someone is wondering. I went and installed the version 20210111, did not install mcu. Things seem to work okay.
Thanks.

Root new Android 7 stock ROM

Hi everyone!
New Android 7 Developer RUU is out. I remember that there were several problems with the last Android 6 security updates in September and October. So it wasn't possible to root with the latest SuperSU.zip
Instead you had to use an older version and update to the latest version with Play Store later.
Before I flash the Android 7 RUU, I would like to know if anyone already has experience with rooting latest Stock ROM?
Any problems which occurred? And if the root process was successful, which SuperSU Version have you used? Thanks in advance!

I've used this to root stock Nougat ROM and it worked fine https://download.chainfire.eu/1014/SuperSU/SR5-SuperSU-v2.78-SR5-20161130091551.zip
Anyway make a backup.. just in case it doesn't work
EDIT: It will reboot the phone at least 2 times before booting into system

No there's no need, at least I didn't change anything and it worked well
I just wanted to add this as a note as I did not see anyone else having these issues in nougat (7.0). Do not install SuperSU 2.78-201609011115. If you do your mobile data option in the notification bar will be grayed out. Your cell signal will have a slash through it and cell signal will no longer work. I do not know if other versions of SuperSU will also cause this symptom.
If this happens to you restore from a backup in recovery or if need be run the RUU again.
Mat08.cc's linked version of SuperSU does work!!!! Thanks!
My m9 doesn't want to upgrade. After it download the Nougat ,it says that I'm running modified system. My phone is att but converted to developer edition. The way I was updating my phone each time so far was with RUU file and I didn't gave any issues until now. Please help . Thanks in advance.

Excuse me, I did not understand.. The phone has received the upgrade but can not install it?
Yes, that is correct. The issue was that my CID was 11111111. Changed it to BS_US001, downloaded, installed successfully. Now I just ran in another issue. Tried to root it so I did: twrp 3.0.2, then installed supersu-v2.78, device booted, cinfirmed rooted but doesn't recognize that there is a sim card inside. Ideas? Thank you!!!

Definitely an incorrect SuperSU apk. Use the one in OP of http://forum.xda-developers.com/one-m9/general/nougat-coming-t3513698
Okay. Will try and get back to you. Thanks
P. S. Am I the only ine who is experiencing Messages failing and sending reports to HTC? Ever since I switched to Nougat, every time when I receive/send a text the app fails and when I try to access notifications it fails automatically as well. Ideas? Thank you

Reporting back:
After installing the SuperSU that you gave, everything works normally. Thank you very much.
There is an update which my phone didn't want to install. It said that the update is for himaulatt and my phone is himaul. Is it because phone is rooted and with twrp recovery? When I install the update manually via RUU from laptop, works fine. It just pisses me off cause I have tk start from scratch with my phone but update is successful. Had this issue for a while now amd was trying to figure it out. I really don't want to keep wiping the phone every single time there is an update. Thank you in advance.
Best Regards

Doesnt rooting void official oxygen updates?

Hello, so i 've been on oxygen 4.0 on my OnePlus 3 for about a week now, and flashed that version via new TWRP. I am rooted with custom recovery. But just now browsing website, and I got a notification that update is available to 4.0.2 lol. OFFICIAL UPDATE. I thought that it is not possible to get official updates when rooted/with custom recovery. Is there something wrong going on? Should I Update? When I was on Oxygen 3.2.8 I wanted to get update using VPN, but had no luck, notification never appeared. Should I officially update this official oxygen 4.0.2 version? is it safe? I don't want to brick my OP3 :/
Don't, I was on the same position and I did and now I have soft bricked my phone and I am here looking for a solution.

just found out that flashing anything under 1gb officially, while you are on TWRP will lead on soft brick. So you will have to flash full OTA zip on your TWRP recovery to fix. BTW, what is your TWRP version? thanks

Actually, I just fixed it and came here to let you know , all I needed to do (I am not an expert on these stuff so it took me a while), is to install an updated unofficial TWRP to avoid the pattern bug, because it kept TWRP from reading my internal storage, once I fixed that the phone turned on with the newer 4.0.2 version.

What version of firmware do you have, and which version of TWRP did you flash? Did you read the TWRP thread and the one I linked you? If on Nougat you need the latest unofficial version of twrp.
Twrp thread:
https://forum.xda-developers.com/htc-10/development/recovery-twrp-touch-recovery-t3358139
Not sure which YouTube vid you followed by I would guess it's probably a bit outdated by now.

And thank you for helping
MS lost and users too !!!
It happened to me yesterday (March 4th,2016) and I did not succeed with anything I tried.
I'm traveling and only return on Monday.
My desktop is with windows-10 educational.
These unannounced automatic updates are horrible, from December to March there have already been 5 major updates, the 24/12 had been the worst of them.
If I have to re-install it I will go back to Windows 98 !!!
MS has totally lost its way, so I do not recommend using Windows-10 that only has spys and telemetry (120 processes running, it's impossible)!

RETUS Nougat Firmware Package?

I've been searching high and low for a full nougat firmware package for the RETUS model... and i cant find one. Has anyone else found one?
I know there are OTAs out there, I'm looking for an FXZ that can be used with fastboot.
filefactory, mirrors.lolinet, etc... seem to have most 7.0 firmware packages EXCEPT for RETUS which only have 6.0 packages.
I have not seen a release for RETUS as of yet... did you not make a nandroid of your original stock before you started flashing...?
If not, flash the 6.0 and the updates found here on XDA.

I haven't unlocked or flashed anything yet... I wanted to try and find an up to date firmware package to have on hand before I start flashing anything.
Do you know if there would be an issue with using the latest 7.0 RETAIL firmware package on my RETUS device?

I'm still trying to wade through all these posts about firmware packages and the lost imei issues.

Sorry to bump this thread, but I tried to root my 7.0 retus yesterday and it is now bootlooping and not working pretty much at all. I am having the same problem with being unable to find stock 7.0 retus fastboot firmware. Did you ever find a solution? Did you just install the retail version, or did you find a fastboot file?

So I am on Retus and upgraded to April patch. Then I unlocked bootloader (successfully), flashed newest TWRP (successfully), flashed the f2fs patch kernel for 7.0 (successfully), then finally Magisk's newest stable (successfully). Phone booted up fine. I went into settings and tried to factory reset, and when the phone rebooted it went to recovery and then now it just doesn't ever boot. It just bootloops. No idea why that is happening.
I found a thread that has steps to downgrade to MM (without flashing bootloader or modem or things that would possibly hard brick) and then after the downgrade I can sideload the Nougat update.
I've seen a lot of people saying if you downgrade after April patch you may hard brick your device, which I am definitely trying to avoid. So if you have any other ideas or if you think what I'm doing is fine, any advice is appreciated!

I might try that instead of taking the risk of downgrading. This seems to be much better. Do you know if I would still get OTAs going this route?
Nice!! Never found anyone else on here that likes that music. I've seen them live and met them twice, they are amazing.
Does anyone know where to get the latest either RETAIL or RETUS stock firmware with the May 1st security update? NPN25.137-24.4

I've been there done that that's for sure. I just bricked one of my Moto Z plays last week doing what you were about to do.
StOP!!!! If you are on Custom firmware above 6, for the love of everything holy and merciful DO NOT downgrade so you can get the OTA. Some of us have and we are waiting for blankflash files that don't even exist yet.

Updating to nougat

Hello All!
I'm sorry if this has been asked before but I'm trying to install nougat on my phone and having some great difficulty.
So far my phone is flashed and I was running TWRP 3.0.2 however every time i try to flash a lineage 14.1 based rom it would never work. (tried straight lineage 14.1, nutOS, DOT) none of them worked (wiped the phone clean, then received error 7, removed the assert lines that let in install but just perpetually boot looped) . My many a google searches makes me believe that that particular version of TWRP does not work with nougat. but that's the only version I am able to get working. any newer version of TWRP gets stuck in a perpetual boot loop.
So with that said, if my suspicious are correct and i need a newer version is there anything I'm missing to install a newer version of TWRP? if 3.0.2 is a good enough version to install nougat based rom's what am I missing on that end?
Any help at all would be greatly appreciated! and Thanks in advance!
Ninja edit: I'm runnnig the Z00A (Z551ML) and i've been using using roms/images meant for Z00A
I'm actually not yet used to these kind of stuffs but I guess your problem has something to do with either your twrp version or the bootloader version, this link might help you. http://theflamingskull.com/downloads/z00a/MM_BL_STUFF/

Yup that was it. My google-fu is off as i found my answer from a reddit post (5 seconds after asking this question in reddit...) My issue was that i was still on lolipop, the last OTA update and had no idea asus put out a manual update. worst part is, after unlocking the bootloader installing twrp, THEN installing that oem update, that might have cause my phone to crash mid update so it ended up bricking the phone...
I was able to Frankenstein it back together with old parts that I thought were no good, right now I'm on that last manual update and I gotta fight through a few issues preventing the boot loader from being unlocked.
Anyway you were correct, using the last OTA update updates the bootloader so I was stuck cause of that.
